When Scalise first arrived at the hospital, "he was in critical condition with an imminent risk of death," Dr. Jack Sava, the director of trauma at the MedStar Washington Hospital Center, said in a press conference Friday.

Scalise "sustained a single rifle wound that entered in the area of the left hip," Sava said, adding that the round fragmented and did "substantial damage to bones, internal organs and blood vessels."

The alleged shooter, identified by police as James Hodgkinson, 66, of Belleville, Illinois, was killed in a shootout with police Wednesday morning after shooting Scalise and three others. Hodgkinson's wife emotionally told reporters Thursday, "I can’t believe he did this," saying there were no signs.
